SETH A. CRONE, OF EAST ORANGE, NEW JERSEY, ASSIGNOR TO BUFFALO BRAKEBEAMCOMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

RAILWAY BRAKE-BEAM MECHANISM.

Application filed January To all whom t may concern.' f

Be it known that I, SMH A. CRoNn, a citizen of the United States, andresident of East Orange, in the county of Essex and State 'of NewJersey, have invented certain new and useful Improvements in RailwayBrake-Beam Mechanisms, of which the following is a specification.

The invention pertains to railway brake beams, and particularly tosafety means applied to the spring plank or other transverse portion ofa car truck for preventing the brake beams from, under anycircu1nstances, riding upwardly over the wheels of the truck or fallingdown upon the road-bed,

said means comprising at each side of theV truck longitudinal safetybars which extend below the end portions of the brake beams and guardbars which extend longitudinally above the end portions of said beams,the guard bars preventing the brake beams from riding unduly upwardlyand the safety bars serving to catch the brake beams should they becomeunhung and fall down.

In carrying out my invention I secure to the bottom of thespring plank,at each side of the truck, a supporting bracket which properly receivesportions of the guard bars and portions of the safety or emergency bars,said guard and emergency bars being` secured within the supportingbracket by means of a transverse pin or pins of wedge nature driventransversely through holes 1n..

the depending side members of the supportling bracket and v-very firmlybinding said bars in rigid relation toeach other and to said supportingbracket.

The invention will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which:

Fig. V1 is alongitudinal section through a portion of a car truckequipped with the brake beam features of my invention, the section beingon the dotted line 1 1 of Fig. 2; f

Fig. 11 is a toplview, partly broken away, of a car truck showing theguard bars and safety bars of the present invention at each sidethereof.

In the drawings 15 designates a portionv of the well-known channel formof spring plank constituting a portion of a car truck frame of usualtype, 16 a'supporting bracket of inverted channel form secured to saidspring plank by rivets 17, 18 a safety or emergency bar held at itsmiddle portion within said supporting bracket, and 19 a bar also Ysecured within said supporting bracket and having upper longitudinallyextending guard members 20, said members 2O constituting guardfbars andthe other portions of the bar 19 serving as the connecting andpositioning means for the bars 20. The bar 18 may be in one longitudinalpiece, as shown in Fig. 1, or in two pieces, as shown in Figs. 7 and 9,andy either event the bar or bars extend longitudinally of the car truckand at their exposed end portions serves as separate emergency or safetybars 21. The bars 20 extend over and the bars 21 below the end portionsof the inside hung trussed brake beams 22, each comprising the usualcompression member 23 and tension 24, with the other Fig. 9 is avertical longitudinal section,l

VYteilige. Y1% to 6 inclusive, it may-be seen thatl low-'recesses ordepresssionsl forniedintlie usnalifv features yof trussedi brakeY beams.The bars20, 21 and their cooperating features are duplicated at oppositesides of' thetruck, asshownfin 1.1.

The supporting bracket 16 is `of wrought metal and of inverted channelform and has a top 25 and depending side members 26 which -are parallelwith each other and properly spaced apart toreceive the' 'safety` barsand middle portien of the bar 19 which affordsthe guardbar members 20.Referring the'lower'edges ofthe depending rsides 26 yof the supportingbracket '16- arefianged? inlwar'dly toward each-other, as at 27", toprovide guiding and supporting lchan-nels forv l tlieloweredges' of thesafetyjbar 18. The

supportingbracket 16 is firmly riveted to thefspringfplank 15by rivets17, which also secure thefguard bar 19 against the ilower surfaceof thetop of said bracket, said rivetsextending Ythrough holes in the springplank, in the top of the bracket 16 andkin thebar 19 and being headedonl both ends.-

`4The flanges 27 ofthe supporting bracket 16 areV cut away, as shown inFigs. 3 and 5,

below the rivets 17 so as tofprovide facilitiesfor the introduction offatoolupwardly. to the "lower `ends ofthe' rivets 17, this being tofacilitatethe riveting operation. The

p sides 2 6fof the bracket 16are prefer-ably embossed inwardly, asiat'l(Figs. 11", 3, 6)', to form inwardly extending flanges directly at vtheupper side edges of the bar 13S, `these flanges serving as guidesintlie'positioning of the bar 18and as shoulders keeping said 'bar downupon the flanges 2'?. In forming' the embossments 13 l first cut holesint the sides 26 and rthen force the metal aroundtlie holes inwardly tocreate theembossinents.A

The guard'bar 1,9 is preferably of inverted `channel forni incross-section and, as

"aforesaid, is secured in` positionjbythe saine rivets ythat secure the'supporting bracketV "16 to the spring'V plank 15. rlkhepbar 19 isstraight at its middle portion'within-the supe porting bracket extendsupwardly, as at 29, and

i then longitudinally to form the oppositely 'beanie' 22.

' extending guard 'members 20, fone. of said members ext'rnicliiigvreariifardly andy the other forwardly. The-bar 19 niaybejof'` anyconvenient shape in cross-sectiombut lflnd Vthat the invertedchannel'shape for'fthi's bait possesses manyjadvantages in the way orsecuring adequate 'strength' and rigidity without undue weight of`metal. is shown inFig. 1A the portions 29 of the bar 19y are closeagainst the vertical sides of the spring plank 15,'whence the members 20curve wardly and outwardly andl extend on the saine' horizontal" planelabove the brake The safety bai-'18 is preferably of intertedchannel-shape in cross-section, and prefera-bly contains in its top alongitudinal topfoffthe bar 18, as 'shown in F 3 and ll.

'The pin Sois of substantial dimensions, and

soL

it has aitfapered forward Vend 32 and is apertured at said end, as toreceive a cottcr key, if desired. rllhe' pin 30 has a driveefit betweenthe upper transverse edges of the bar 1'8,lthe lower edges of the bar 19and fthe edges of the holes in said member 26 through which said pin isdriven. The taper on the forward end of the pin 50V is to'perniit thatend of the pin to pass'below the lower far edge ofthe bar 19 and findits way into the hele inthe far side of the bracket 16. The' pin 4hasa'binding action against`v thebar 18 to clamp it downwardly ywith greatvfirmness upon thesupporting flanes 2f?, and by reason of the recesses 31formedkv 1n' the bar l18,1said bar haslan inten y 'locking engagementwith lthe pin 3() which securesthe bar against endwise movement.

I preferably equip the pin 30 with a lock Slto prevent the esca-pe ofthe piiifroin its rpositioninsupporting the bracket 16 should therebe noCotter keyrpresent at the -hole 33, either =byreason rof inadvertence oraccident,

and Vthis lock 84 consists simply ofy a strip lof sheet metal bent to.forni a vert-ical meniber 35,'avertical member 36, a: lower member 3?connecting said ineinbers 35, 36, and a' niember''S extending from theupper end of the member 36 and bent downwardly against Yinl Figs. 1 to 6inclusive, the barV 19, supc porting bracket 16'a1id spring plank 15 aresecured together as-one ijnt'egial structure by means ofthe rivet 17,while the single bar 18 is supported within the bracket.: 16 and rigidlysecured therein by means of a single pin 30. I preferably form the bar18of such length that "it 'may vextend longitudinally in oppositedirections beyond the bracket 16 to a sufficient extent to forni theemergency Ior safety bar members 21. lVhenever desired f the pin V3)()may bewithdrawn so as to permit of thesliding ofthe bar 18 in onedirection or the other or its withdrawal entirely aS lll() theY` outerAfaceofthe head 89L of thevpinythe/- may be convenient for such occasionas may arise with respect to the brake beams 22.

The' construction describedis one of greatstrength, durability andrigidity, and is of simple nature and capable of being readily appliedto cartrucks.

|The construction shown in Figs. 7 and 8 is much the same as theconstruction shown in Figs. 1 to 6 inclusive, the main differencestruction shown in Fig. 7, the safety bars V are in two separate piecesor members 40, this feature rendering 1t necessary to employ two of thewedge pins 41, one for each of said bars.

Thespring plank 15, bar 19 and supporting bracket, in this instance 42,are all secured together by the rivets 17, as shown in Figs. 7 and 8. AI number the supporting bracket as 42, the construction having beenchanged from that shown in Fig. 1, to the extent of having holes formedthrough the side members thereof to receive the two pins 41. The meetingor inner end portions of the emergency or safety bars 40 are belouelongated embossments or in-l wardly pressed flanges 43, as shown inFigs. 7 and 8, these embossments of flanges aiding in the positioning ofthe bars 40 and affording bearings above the adjoining ends of said barswhich would prevent down pressure applied on the outer end portions offlanges corresponding exactly with theA flanges 27 shown in Figs. 4 andThe purpose of presentingFigs. 7 and 8 is to indicate that the safetybar members may constitute one integral bar, as shown in Fig. '1, or bein two separate pieces, each independent-ly secured in position, asshown in Fig. 7 l f In the modification shown in Figs. 9 and 10 I makeno change in the spring plank 15, bar 19 or rivets 17 but slightlymodify the details of the supporting bracket 46 to permit the lockingpins 47 to pass below the l co same.

safety bar. members 48 instead of above the In the construction shown inFigs. 9 and 10 the safety bar members 48 are straight and their upperedges at theinner ends thereof are against the lowery edges of Y the bar19 and their lower edges within the supporting br`acket46 are recessed,as at 49,

y and engaged by the wedge pins 47 tol bind the inner .end port-ionsr ofthebars 48 upwardly against the bar 19. lllVhen the pins 47 are belowthe safety bar members and wedge said membersupwardly, it is notnecessary that the supporting' bracket be provided with flanges such asthose numbered 45 in Figs. 7 and 8. The construction shown inFigs. 9 and10 will be'readily understood from the detailed descriptionshereinbefore presented. The construction shown in Figs. 7, 8, 9 and 10will preferably be provided with pin locks 34 of the characterhereinbefore described. y

Then the emergency safety bar for each side of the truck is in oneintegral piece, as shown in Fig. 1,-I will preferably provide each barwith mea-ns for preventing it from sliding out from the supportingbracket 16 in the event that the securing pin18 should be inadvertentlyomitted or should rbecome lost'from the bracket, and in car'- rying outthis feature of my construction I will slit tongue inv the side of eachend of the channel bar 18 and, after the bar has been inserted into thebracket 16, bend the tongues laterally to form projecting lingers orVstops 14 adapted to engage the end of the bracket, should the bar bejai-red to slide endwise, and retain said bar against escaping whollyfrom the bracket.

The emergency bar 18 is ofrolled metal,v

and hence the fingers 14 may be bent outwardly therefrom 'after the barhas vbeen introduced into' the bracket 16, and may also be bent backinto the body of the bar at any time it might become necessary to re'-move the bar fromthe bracket. I

In cach of the constructions described the spring plank 15, bars 19 andsupporting brackets are, at each side of the car truck, all securedtogether by means of the rivets 17, `and in each of said constructionssafety through the Vsides of the supporting brackets and engaging saidmembers with binding effect.

rlfhe spring plank 15 is one of many known forms of spring planksdiffering in details from` one another but performing like duties. Myinvention is not limited to the details of any special spring plank, andtherefore I Vemploy the designation spring plank in this application inla generic sense.
